Abstract
The increasing volumes of mining work at the Solntsevsky coal mine have revealed a number of problems, the solution of which will affect the implementation of the plan to annually increase coal production to 20 million tons and above. This article discusses some of the issues on improving the drilling and blasting process through the introduction of joint blasting technology and improving the quality of the charge of bulk emulsion explosive in flooded wells and other issues to reduce the downtime of machinery and equipment, reducing the radius of the danger zone for the scattering of pieces of blasted rock mass. In the process of research work, it was possible to solve some of the problems with the assistance of the Institute of Mining of the Far Eastern Branch of the Russian Academy of Sciences and contribute to the record coal production expected in 2023 - 13.7 million tons.
Keywords
Reducing the downtime of machinery and equipment, the radius of the danger zone, methods for improving drilling and blasting operations, joint blasting technology, the quality of borehole charges of emulsion explosives.
